ABV® for OTS Spectrum Full Face Mask
The Spectrum ABV is positioned on the side of the mask – not to interfere with the field of vision – and is very easy to operate. It gives the diver ambient air while on stand-by or at surface level.
The ABV has a small form factor and will not disturb the diver above or under water. The design of the valve keeps the breathing resistance extremely low. Ambient breathing will not only increase cylinder duration time but will enable the diver to keep the face mask donned while on stand-by.
